communicate :: collaborate :: commemorate

I recently had some intelligent conversations in Signal and in one of them I explained that I do not consider my email as confidential, but I do with chat. Email is a store and forward system and while it may be encrypted in transit it is not encrypted at rest. And I cannot be bothered with PGP. While I do not disclose secrets on purpose, I also cannot protect them. Email gets replied to and forwarded and such things. You would not believe the amount of confidential information I gathered by just scrolling down.

Chat = confidential, email not so much.

For chat to stay confidential it has to be encrypted. In transit and at rest. Signal does that for me. Since the last time I asked, my contact list has grown by 100 people. And that is only the people I know of. My phone number is public. Add me to your address book and you can reach me on Signal.

If you want me to be able to reach out to you, or to even recognize you when you contact me, I need your phone number. The best way to tell me your phone number is by emailing me your vcard. What does a good vcard look like? Here is an example. It's just a text file with the extension .vcf.

However, I am not quite sure I follow your logic to consider chat to be that more confidential. What prevents a Signal user from copying and forwarding content from your Signal chat messages? Admittedly, forwarding the whole conversation is not a simple click of a button as it is in e-mail and thus it won't happen as accidental as it probably does in e-mail. But calling it confidential seems a bit far reaching.

One really has to go a lot further than that when you want to ensure that usage permissions are enforced on content.

The one big disadvantage of signal seems to be that you cannot send file attachments other than videos or images. No PDF for example. Would be great if signal would allow for a encrypted way of transferring documents (only up to a reasonable size of course)

I think it would also help if it was possible to add them in Facebook, Google+ and other profiles. Unfortunately neither Facebook nor Google+ allow you to do so in their dropdowns (but instead some others I've never heard of....)
